FLATstrap Launch Party
Description
The FLATstrap is a chest-minimizing shapewear undergarment made for comfort and self-expression. On Sunday, November 15, we're launching it with a four-hour party at The Rotunda.
Come get fitted for powerful pecs, meet the people who helped shape it, watch a great lineup of performers, and take a deep belly breath in a room full of people who are glad you're here.
The party is also a fundraiser for our Share It Forward Model, an affordability program that will offer free units to queer and trans people who can't afford the current price. Every ticket helps.

What's happening
Get fitted. Private spaces will be set up for fittings, so you can try the FLATstrap on at your own pace. A rack of styles will be on hand so you can see how it sits under shirts, jackets, and whatever else you want to wear over it.
Get your photo taken. The photo booth is the place to try the FLATstrap on and strike a pose, if you want a picture of the moment. Sharing is always your choice, and we only post photos of people who say yes. Nobody takes photos in the fitting spaces.
Make a packer. Darb Garb is running a crafting station where you can learn to make your own whimsical packer.
Watch the show. Edith Poussard hosts an afternoon of live performance, with sets of 5 to 10 minutes so something new is always starting. Naija Couture/Adonis is on the decks playing jams all afternoon.
Eat something. Catered bagels and fixings will be out all afternoon.
Reserve yours. If you like how it feels, you can pre-order a FLATstrap at flatstrap.euphorm.co. Pre-orders are guaranteed to be fulfilled before the end of 2026.
Lineup
Host: Edith Poussard
DJ: Naija Couture/Adonis

How tickets work
Tickets are pay what you can, on a sliding scale from $0 to $50. Nobody is turned away for lack of funds. If you can pay more, you're helping cover the guests who can pay less. If money is tight, choose $0 and come anyway.
To help you decide, here's how we think about the common levels: $15 if you can pitch in a little, $30 if you want to cover your own seat, and $50 if you'd like to help cover someone else's.
Everything raised goes to our Share It Forward Model, which helps close the affordability gap by offering free units to queer and trans people who can't afford the current price.
Walk-ups are always welcome.

FAQs
- Do I need a ticket?
Tickets help us plan for the room, so we'd love you to reserve one. Walk-ups are welcome too.
- What if I can’t pay?
Choose $0. No proof and no explanation needed.
- Where does the money go?
Everything raised goes to our Share It Forward Model, which helps close the affordability gap so the FLATstrap is available to queer and trans people who find the current price out of reach. Ticket proceeds and our ongoing fundraising will help us offer free units to people who need them. The party also kicks off our online Share It Forward campaign, so if you can't make it you can still contribute at flatstrap.euphorm.co/giving. Contributions aren't tax-deductible yet, because we're still working on a nonprofit fiscal sponsor.
- Can I just come to watch?
Yes. Fittings, the photo booth, and the craft table are all optional.
- How do I find my size?
FLATstrap sizing is based on your underbust rib circumference and chest apex measurements. There are five adjustable sizes covering xS to 3xL. Measure ahead of time and bring the numbers with you, or we can help you measure at the party in our fitting booth area.
- Will I be photographed?
Only if you step into the photo booth and say yes. At the door you'll pick a colored sticker (green means photos are fine, yellow means ask first, red means keep me out of photos), and nobody photographs the fitting spaces. Photographers ask before posting anything. Photos and videos of kids show the back of the head only, with no faces. A sign at the entrance explains the stickers.
- Can I buy a FLATstrap there?
You can be fitted at the event and pre-order at flatstrap.euphorm.co, with delivery guaranteed before the end of 2026.
- Is the venue accessible?
Step-free entrance by the ramp on the west side of the building (right side, toward the back). The east entrance has 7 steps. A single-stall, all-gender, wheelchair-accessible restroom with a baby changing table is on the first floor near the ramp entrance, and the stage has a ramp at stage right. Two more all-gender restrooms are in the basement, and there is no elevator. Chairs are available on request.
- How do I get there?
SEPTA bus routes 21, 40 and 42, the Market-Frankford Line to 40th and Market, and trolley lines 11, 13, 34 and 36 at 40th Street. Street parking is free on Sundays on 40th, 41st, 42nd, Walnut, Locust and Spruce, and there is a paid garage at Acme on the northwest corner of 40th and Walnut. Three bike racks are on site.
- Is there anything else I should know?
Space is limited. Please stay home if you feel unwell or have been in contact with someone diagnosed with Covid up to 10 days before the event. If you come down with Covid symptoms up to 10 days after attending, please let The Rotunda know at information@TheRotunda.org. They will never share your name or personal info.
